Pacific Performance Engineering Exhaust Manifolds
Replacing your stock exhaust manifold and up-pipes should be the first step in building a high performance exhaust system. Pacific Performance Engineering exhaust manifolds are co-designed by Honeywell (Garrett) and PPE, using CAD software to maximize flow characteristics. The included up-pipe bellows are high-flow, internally sleeved, and manufactured from 11-gauge, 0.120 in. wall aircraft-grade stainless steel with a 2 in. O.D. The exhaust manifolds are machined from high-silicon moly cast iron; feature built-in bosses; and are pre-drilled and tapped for a 1/8 in. NPT EGT sensor. PPE exhaust manifolds will help lower exhaust gas temperatures, reduce drive pressure, and accelerate turbo spool-up while maintaining reliability. Order the model recommended for your application.

Pacific Performance Engineering Replacement High-Flow Up Pipes
Pacific Performance Engineering replacement high-flow up-pipes allow as much as 53 percent more flow than stock pipes, and they're a direct bolt-on to your factory manifolds. Diesel engines, even stock, produce high temperatures and pressures. OEM up-pipes eventually fail from constant temperature and pressure fluctuation. Unlike factory parts, these OE replacement high-flow up-pipes are manufactured from 11-gauge 304 stainless steel. They include internally-sleeved bellows that can take the abuse of high temperature and high pressure. Order the model recommended for your application.

Pacific Performance Engineering Exhaust Reducers
Pacific Performance Engineering offers exhaust tubing reducers for a wide range of applications. Constructed of robust 2mm thick 304 stainless steel, the reducers have a gradual radius profile for efficient flow of exhaust gasses. Their smooth transitional shape is superior to the typical hard angle of similar reducers that can cause exhaust gasses to tumble, which reduces performance.

Pacific Performance Engineering Exhaust Manifold Hardware
Pacific Performance Engineering offers exhaust manifold hardware for a variety of applications, including many Chevy, GMC, Dodge, and Ram from 2017 and up. Upgrade the rusty or broken manifold bolts on your Cummins 5.9L/6.7L or GM 6.6L Duramax L5P. Over time, repetitive heat cycles can take a toll on factory bolts, causing fatigue and stretching—ultimately resulting in troublesome exhaust leaks. Each replacement stud is centerless ground and rolled with extreme precision, reducing stress concentrations and increasing durability. The use of studs and nuts allows for torque reading and more even load distribution. Duramax kits include 16 class 10.9 chromoly alloy steel studs and nuts for both stock manifolds. Cummins kits include a dozen bolts, 12-point flange head nuts and washers. All hardware is finished in a black oxide coating for rust prevention. The hardware features a 180,000 psi tensile strength.
